Active Control of Structures Review

Active Control of Structures
Average Reviews:

(More customer reviews)
One of the authors, Prof. Seto, has been leading active control technology development in Japan for more than 20 years. The latter half of this book is full of his experiences applied to tall buildings and long span bridegs. Illustrations of these successfull applications are good part of this book. Unfortunately, applications to motor vehicles and aerospace structures are not disclosed. The theories introduced in this book is relatrively easy to understand even for college students. The reason may be because the theory the authors used is a little bit classic. So, if you like mathematics, then this book is not for you. However, if you are engineers who seek real things, you should read this book.

With Active Control of Structures, two global pioneers present the state-of-the-art in the theory, design and application of active vibration control. As the demand for high performance structural systems increases, so will the demand for information and innovation in structural vibration control; this book provides an effective treatise of the subject that will meet this requirement. The authors introduce active vibration control through the use of smart materials and structures, semi-active control devices and a variety of feedback options; they then discuss topics including methods and devices in civil structures, modal analysis, active control of high-rise buildings and bridge towers, active tendon control of cable structures, and active and semi-active isolation in mechanical structures.
Active Control of Structures:
Discusses new types of vibration control methods and devices, including the newly developed reduced-order physical modelling method for structural control;
Introduces triple high-rise buildings connected by active control bridges as devised by Professor Seto;
Offers a design strategy from modelling to controller design for flexible structures;
Makes prolific use of practical examples and figures to describe the topics and technology in an intelligible manner.

Transfer function form, zpk, state space, modal, and state space modal forms. For someone learning dynamics for the first time or for engineers who use the tools infrequently, the options available for constructing and representing dynamic mechanical models can be daunting. It is important to find a way to put them all in perspective and have them available for quick reference.It is also important to have a strong understanding of modal analysis, from which the total response of a system can be constructed. Finally, it helps to know how to take the results of large dynamic finite element models and build small MATLAB state space models.Vibration Simulation Using MATLAB and ANSYS answers all those needs. Using a three degree-of-freedom (DOF) system as a unifying theme, it presents all the methods in one book. Each chapter provides the background theory to support its example, and each chapter contains both a closed form solution to the problem-shown in its entirety-and detailed MATLAB code for solving the problem. Bridging the gap between introductory vibration courses and the techniques used in actual practice, Vibration Simulation Using MATLAB and ANSYS builds the foundation that allows you to simulate your own real-life problems.FeaturesoDemonstrates how to solve real problems, covering the vibration of systems from single DOF to finite element models with thousands of DOFoIllustrates the differences and similarities between different models by tracking a single example throughout the bookoIncludes the complete, closed-form solution and the MATLAB code used to solve each problemoShows explicitly how to take the results of a realistic ANSYS finite element model and develop a small MATLAB state-space modeloProvides a solid grounding in how individual modes of vibration combine for overall system response
